Merge tag 'block-7.4-20261106' of git://git.kernel.org/pub/scm/linux/kernel/git/axboe/linux

Pull block fixes from Jens Axboe:

 - NVMe fixes via Keith:
    - nvme-tcp use-after-free in nvme_tcp_free_ctrl() on a failed
      connect, and the nvme-rdma counterpart of the NULL queue->ctrl on
      reconnect
    - nvmet-rdma iWARP disconnect and device removal fixes
    - nvmet-tcp: ask for the TLS record type on every receive, and bound
      the connections accepted per work run so a connect flood can't
      hold up port removal; nvmet-auth keep the old keys if the new ones
      fail to decode; nvme-loop delete the controller if a reset fails
    - nvmet-auth reject incomplete DHCHAP messages, and a keep-alive
      timeout overflow
    - nvmet locking and bounds fixes for tbkas reconnects and the
      traddr/trsvcid configfs writes, don't leak stale memory in the ANA
      log page, and cache the passthru reference across queue_response
    - Wait for SRCU readers before splicing the namespace list, with a
      new list_splice_init_srcu() helper, and drop an extra grace period
      in nvmet_ns_disable()
    - Unregister when pr_register() is given a zero new key, and don't
      drop the cdev reference twice on cdev_device_add() failure
    - Quirks for the ADATA XPG GAMMIX S70 BLADE and KIOXIA XG10d
    - Various smaller fixes and cleanups

 - blk-mq: end the request if getting a keyslot fails, which left the
   in-flight count and zone write plug stuck, reset the queue state on
   scheduler teardown so requests don't stall in software queues, and
   fix an out-of-bounds read in blk_mq_free_rqs() after a failed
   nr_hw_queues update

 - Only serialize elevator switches of the same queue

 - dma-buf bio fixes: don't use the bvec fast path for them, and only
   fail the ones that need block layer PI

 - Reject GPT entries with starting_lba > ending_lba

 - Return the soft block size for compat BLKBSZGET, report the correct
   discard alignment in sysfs, and account the flush sequence latency
   only once in iocost

 - virtio_blk fixes: synchronous quiesce in freeze, freeze the virtqueue
   layout at probe time, clamp max_segments to the ring size, and fix
   zone append sector reporting in batched completion

 - null_blk zone fixes and a cache state reset

 - zloop fixes

 - ublk DEL_DEV_ASYNC permission check, and 32-bit selftest build
